The acceleration of an object is approx 9.8 meters per second, per second. I.E. at the end of the first second 9.8 meters, second second 19.6 third second 29.4... this is ACCELERATION, there is also drag (Friction)on the object in a medium, that will limit the speed somewhat hence why an object with a round parachute "Falls" slower... and Terminal Velocity is when the drag equals the force of gravity through a medium... say a person jumps off a six foot ladder, and someone dives off a ten meter platform... the person on the platform will hit the water at a higher rate of speed than the person on the ladder will hit the ground... but... someone falling from say 30000 feet will not make a bigger crater than someone falling 3000 (1/10th the distance) their speed will be equal...
